（Python代码）

闲的没事，想做一个Python爬虫气象站

源代码：

from tkinter import *
from bs4 import BeautifulSoup
import requests
root = Tk()
def findweather():
    responce = requests.get("http://www.weather.com.cn/weather/101121201.shtml")
    responce.encoding="urf-8"
    soup=BeautifulSoup(responce.text,"html.parser")
    div=soup.find("div",id="7d")
    ul=div.find("ul")
    li=ul.find_all("li")
    weatherForSevenDay=[]

    for weather in li:
        temp=[]
        date=weather.find("h1").string
        temp.append(date)
        p=weather.find_all("p")
        weatherDetail=p[0].string
        if weatherDetail is not None :
            temp.append("天气为：%s" % weatherDetail)
        Hightemprature=p[1].find("span").string
        if  Hightemprature is not None :
            temp.append("最高温为：%s ℃" % Hightemprature)
        Lowtemprature=p[1].find("i").double
        if  Lowtemprature is not None :
            temp.append("最低温为：%s ℃" % Lowtemprature)
        weatherForSevenDay.append(temp)

        for weather in weatherForSevenDay:
            print(weather)
root.geometry("700x400")
root.title("家庭气象站")
label_1=Label(root,text="家庭气象站—首页",bg="cyan")
label_1.pack(fill = X ,padx=10)
button=Button(root,text="直接显示天气(在Pyhon Shell中查看)",command=findweather)
button.pack()
root.mainloop()

结果报错：

Exception in Tkinter callback
Traceback (most recent call last):
  File "D:\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)
  File "C:/Users/Administrator/Desktop/家庭气象站/家庭气象站.py", line 22, in findweather
    Hightemprature=p[1].find("span").string
AttributeError: 'NoneType' object has no attribute 'string'
